According to the official material, LV520 has three kind of colors to supply the choice at present, red also has the aristocrat black and the gem blue color besides the rose.
The LV520 built-in ring-like radiator, the application sound pressure dynamic low-frequency gain technology principle, increases loudspeaker's air radiating area, obtains a better low frequency lower limit, thus promotes the low frequency feeling of quantity. Its electroacoustical principle and the inverter tube principle are the same, but “the sound pressure dynamic low-frequency gain” a technical more profound significance is volume of electroacoustics, the structural design is a body, is one kind of comprehensive technical application manifestation. Is different with the design ordinary sound box is the low frequency large scale promotion most greatly, effective enhancement low frequency radiating area promotion feeling of quantity.
